API 5L Gr. B MS steel plate equivalent to grade L245

API 5L Gr. B, Gr. B refers to steel grade B. The API 5L standard is implemented. The corresponding Chinese standard of the API 5L standard is GB/T9711, and the corresponding material of Gr. B is L245.

Pipeline steel refers to a kind of steel with special requirements used for transporting oil, natural gas and other pipelines. Depending on the thickness and subsequent formation, it can be produced by hot continuous rolling mill, steckel mill or medium plate mill, and formed into large diameter steel pipes by spiral welding or UOE straight seam welding.

API 5L Gr. B MS steel is mainly used as high-temperature and high-pressure alloy steel pipes for water supply pipes, pipe fittings, bypass systems, etc. In addition, all kinds of pipeline materials are provided in strict accordance with relevant international and domestic standards such as American ASME, ASTM series, German DIN series, and international ISO, Chinese GB series.

Pipeline steel is a kind of steel plate for pipeline, mainly used for processing and manufacturing oil and gas pipelines. In the process of use, in addition to higher compressive strength, it is also required to have higher low-temperature toughness and excellent welding performance.
